Motorola has scored a rare win over Microsoft in an ongoing litigation battle over patent infringement claims in a German court, denying Microsoft a further sales ban against Motorola Mobility's products.

The Mannheim Regional Court ruled that Google-owned Motorola Mobility did not infringe a Microsoft-owned patent. The technology in question describes a series of developer APIs that allow applications to work on multiple devices. But EU Patent No. EP1233343 was not infringed by the Android phone maker, the court said.

But the Redmond, WA.-based software giant said that today's loss does not impact a string of injunctions its against the rival phone maker, which have already been granted and enforced in the country, according to Reuters.

Microsoft and Motorola Mobility remain in the grip of courtroom battles as the companies fight it out over a range of smartphone patents.

The software giant has already won three cases against Motorola Mobility in Germany, which forced the Google-owned unit to pull many of its devices from the store shelves or modify the Android software where software patents were infringed.

Microsoft's chief lawyers said in August that it wants "patent peace," and doesn't want to fight. In a blog post by Microsoft general counsel Brad Smith and deputy general counsel Horacio Gutierrez said that the company "always has been, and remains open to, a settlement of our patent litigation with Motorola."
